Specification of Letters Patent.

Patented Jan. 16, 1906.

Application filed July 30, 1904. Serial No 218,870.

To all whom it may concern:

Be it known that I, RICHARD ,BLAzEJ, a subject of the Emperor ofAustria-Hungary, and a resident of the city of New York, Whitestone,borough of Queens, in the county of Queens and State of. New York, haveinvented a new and Improved V-Block, of which the following is a full,clear, and exact description.

. The object of this invention is to provide a V-block with anattachment enablin a shaft to be drilled transversely with abso ute cer-Y tainty and to render the attachment adjust- Thisable to shafts ofvarious diameters. end I attain by providing a peculiar gage-bar adaptedto lie over the V-block on top of the shaft and connected with theV-block by means of slides mounted thereon. In connection with theV-block Iuse a support having a certain peculiar connection with the V-blslck, enabling its position to be adjusted at W1 The invention residesin certain novel features, which will be fully set forth hereinafter andpointed out in the claims.

Reference is to be had to the accompanying drawings, forming a part ofthis specification, in which similar characters of reference indicatecorresponding parts in all the figures.

Figure 1 is aside elevation of the invention with parts broken away.Fig. 2 is a plan view of the V-block. Fig. 3 is an end elevationthereof. Fig. 4 is an end elevation of the support, and Fig. 5 is adetail section of thegage*bar on the inc 5 5 of Fig. 3.

indicates a V-block having therein the usual V-notch 11 to receive ashaft, which is shaped, and its an 1c is vertically coincident with theangle of t e \i-notch 11.

'Coactin with the gage-bar 17 is a holder 20, forme preferably, of asection of metal bent to embrace the gage-bar and held adjustablethereon by a set-screw 21 or its equivalent. In said holder is a notch22, reg-.

istering with the notch 19 and adapted to allow the drill to passthrough the holder. this device the shaft may be centered and the drillguided into the shaft intrue central position. By adjusting the slides14 a shaft of any size may be held, and by adjusting the ho der 20 adrill of any size may be employed.

The shaft-holder comprises a block 23, having a notch 24 therein similarto the notch 1 1. A yoke 25 is pivotally mounted on the block 23 bymeans of screws 26 or their equivalents, and said yoke carries a screw27, adapted to be engaged with the shaft, as shown, thus securelyholding the shaft. The blockslO and 23 are connected adjustably by meansof a rod28 extending through coinciding openingsin the blocks, the endof the rod adjacent to the block 10 being threaded and provided with athumb-nut 29 and the opposite end thereof being formed with annularteeth, coacting with which is a sliding lock-plate 30, operating inundercut grooves in the block'23 and capable of holding the rod 28 inany desired position in the block 23. By properly manipulating thedevices 29 and 30 the blocks 10 and 23 may be moved toward or from eachother, as desired, and then looked securely in this adjustment. In usingthe device the shaft, after the blocks 10 and 23 have been properlyadjusted, is placed in the notches 11 and 24, and the screw 27 istightened to hold the shaft in place. The gage-bar 17 is next moved intoposition over the shaft, and then by entering the drill through theopening 22 and guiding it against the walls of the notch 19 the shaftmay be bored accurately, as explained.

Various changes in the form, proportions, and details of my inventionmay be resorted to at will without departing from the spirit and scopethereof. Hence I consider myself entitled to all such variations as maylie within the terms and intent of my claims.

Having thus described my invention, I claim as new and desire to secureby Letters Patent- 1. The combination of a V-block having an openingtherethrough, a work-holding device having a corresponding openingtherethrough, a rod extending throu h said openings and provided withthreads om one end and annular teeth from the other, a nut on thethreaded portion of the rod, and means on the work-holding device forengaging said teeth to'hold the \I-block and saidworkholding device inadjusted relation to each other.

i 2. The combination of a V-block proper, a

' horizontal gage bar, verticallyadjustable .mounted on the gage-bar,and means for securing the tool-holder to the gagebar, the latter andthe toolholder having opposite notches therein to admit anoperating-tool.

3. The combination of.a V-block proper, a horizontal gage bar,vertically adjustable means sustaining the gage-bar over the V- block, ahorizontally-adjustable tool-holder mounted on the gage-bar, and meansfor securing the tool-holder to the gage-bar, the tool holder being U-shaped and fitting thegage-bar transversely thereof, and the latter andthe tool -holder having corresponding notches therein to admit a tool.

In testimony whereof I have signed my name to this specification in thepresence of tWo subscribing Witnesses.

RICHARD BLAZEJ.
